Areas near oceans or large lakes tend to have more moderate climates than do areas far from large bodies of water. which of these statements best explains this observation?

hydrogen and oxygen atoms share electrons in a water molecule.
lakes and oceans contain dissolved solids.
water has a very high specific heat.
water produces buoyant forces.

question 2(multiple choice worth 2 points)

a scientist discovers a new substance. the molecules of the substance form hydrogen bonds with each other. when the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. based on this information, what can the scientist infer about the substance?

it expands when it freezes.
it is highly colored.
it exists only as a gas.
it does not dissolve ionic compounds.

question 3(multiple choice worth 2 points)

which of the following properties of water is due primarily to the uneven distribution of charge between the hydrogen and oxygen atoms?

its color
its taste
its ability to dissolve ionic substances
its ability to produce buoyant forces

question 4(multiple choice worth 2 points)

a drop of water placed on a smooth, dry surface will form a dome-shaped droplet instead of flowing outward in different directions. which of these best explains this observation?

the bonds between hydrogen and oxygen atoms are very strong.
the electrons in the atoms attract the electrons in the other atoms.
water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.
water molecules near the surface produce more buoyant force than water molecules within the liquid.
